What to do if the excavator Hyundai Bucket Teeth fails?

Hyundai Bucket Teeth is an important part of the excavator and also a wearing part. It is a combined bucket tooth composed of a tooth seat and a tooth tip, and the two are connected by a pin shaft. Because the bucket tooth wear failure part is the tooth tip, just replace the tip.

Form of failure

The teeth receive different degrees of wear under different working conditions and environments, and the damage to different degrees of impact is also different. The bucket teeth can only be used for three days under normal working conditions, which is not satisfactory from the economic or use point of view.

Failure analysis

1. Analysis from the aspect of stress

The force area of the bucket teeth is in contact with the object being excavated, and the force is different at different working stages in a complete excavation process. When the tooth tip part first contacts the surface of the material, the bucket tooth tip part is strongly impacted due to the high speed. If the tooth yield strength is low, plastic deformation will occur at the tip. As the digging depth increases, the force of the bucket teeth will change.

2. Analysis from working conditions

When the bucket tooth cuts the material, the bucket tooth and the material move relative to each other, generating a large positive crushing force on the surface, thereby generating large friction between the bucket tooth force area and the material. If the material is hard rock, concrete, etc., the friction force will be great. As a result of repeated processes, different degrees of surface abrasion are generated on the bucket tooth working surface, which in turn results in deeper furrows.

From the analysis, it can be judged that positive pressure and friction are the main external mechanical factors of bucket tooth failure, and play a major role in the process of failure generation.

As a Hyundai Bucket Teeth Wholesale, share with you the problem of slower excavators.

How did the problem of slower excavators arise?

1. The output power of the hydraulic pump is insufficient to determine whether the small excavator is decelerated due to the continuity of the hydraulic pump, test the relevant pressure in the maintenance diagnostic system. You can also determine whether pilot pressure is insufficient, spool valve pressure is insufficient, flow is insufficient, or speed is reduced.

2. Suppose the speed of the excavator is slow. You should carefully check the hydraulic system to see if hydraulic oil is changed regularly. Long-term use of hydraulic oil will not only affect the performance of small excavators but also corrode the hydraulic walls of excavators. Also, make sure that the return filter and hydraulic oil circuit are not blocked.

3. The engine power of the excavator may be very low. This will reduce the output of the excavator, destroy the excavator's brakes, and reduce the overall speed of the excavator. If the engine power is low, you need to ensure that all cylinders run smoothly. Next, carefully check the smoke from the engine. If the injectors are severely worn, the output of the engine will be reduced and the speed of the excavator will be reduced.
